Abstract

A sensor detects one or more hazardous materials, such as by measuring the concentration of one or more hazardous gasses. The sensor or an external system can also determine a location of the sensor. This location can be associated with the measured data from the sensor at the external system or at the sensor. The location could be determined at the sensor using GPS or RFID. The location could be determined at the external system using RFID. The external system can use the measured data and the location information to perform a wide variety of tasks, such as mapping hazardous materials in a processing or other environment or identifying trends in the concentration of the hazardous materials.

a controller configured to trigger an alarm in response to any thresholds violated by the measured amounts of the one or more hazardous materials; and

a waterproof housing containing the sensor, the tracking system, the interface, the control, the display, and the controller, wherein the housing comprises an attachment operable to couple the housing to a moveable object.

2. The apparatus of claim 1, wherein:

the sensor is operable to measure a concentration of the one or more hazardous materials; and

the interface is operable to transmit one or more measured concentrations generated by the sensor.

3. The apparatus of claim 2, wherein:

the tracking system is operable to determine the location of the apparatus; and

the interface is operable to transmit the one or more measured concentrations and one or more determined locations.

4. The apparatus of claim 3, wherein the tracking system is operable to determine the location of the apparatus using at least one of:

Global Positioning System (GPS) signals and signals from one or more radio frequency transmitters.

5. The apparatus of claim 2, wherein the tracking system is operable to initiate transmission of signals used by an external system to identify the location of the apparatus.

6. The apparatus of claim 1, wherein the controller is further operable to control operation of at least one of:

9. The apparatus of claim 1, wherein:

the sensor is operable to measure a concentration of the one or more hazardous materials;

the controller is operable to determine if the concentration of each hazardous material exceeds a specified threshold associated with that hazardous material; and

the controller is operable to trigger the alarm to provide an indication to the user when the concentration of at least one hazardous material exceeds its associated threshold.

10. The apparatus of claim 9, wherein:

the sensor is operable to measure the concentration of each of multiple hazardous gasses;

the controller is operable to determine if the concentration of each hazardous gas exceeds a lower threshold or an upper threshold; and

the controller is operable to trigger the alarm to provide different indications to the user, the indications varying based on whether the concentration of at least one hazardous gas exceeds its lower threshold or its upper threshold.

11. A method, comprising:

measuring one or more hazardous materials at a portable sensor multiple times, wherein at least one measurement is taken in response to manual operation of a control on the portable sensor;

storing measured amounts of the one or more hazardous materials generated in a memory of the portable sensor;
